ceil()                   Calculate Ceiling of Value
 
 #include <math.h>
 
 double     ceil(x);                     Ceiling of value
 double     x;                           Floating point value
 
    ceil() returns a double value of the smallest integer that is greater
    than or equal to 'x'.
 
    Returns:    Smallest integer >= 'x'. There is no error return.
 
  -------------------------------- Example ---------------------------------
 
    The following statements calculate the ceiling of 3.3, 0.0 and -3.3.
 
         #include <math.h>      /* Required for function definition only */
 
         main()
         {
             double x, y, z;
 
             x = ceil(3.3);     /* x = 4.0 */
             y = ceil(0.0);     /* y = 0.0 */
             z = ceil(-3.3);    /* z = -3.0 */
         }
